Ghost Sheep

I was cruising around the the countryside on Friday afternoon looking for something interesting to take photos of.  I was on my way back as it was getting dark, about 4:30 pm this time of the year, when I stopped to take a few pictures of a castle ruin.  Anyhow, I was heading back to the car when I saw something strange in the distance.  It was pretty dark, so I couldn’t see what it was right away but I wandered towards it.  Turned out to be a big herd (flock?) of sheep some field.  Here’s a 20 second exposure of them.  I wish I could have gotten closer but I was blocked by a few fences.
